Step 2: We have a formula for calculating the average slope of a function that is: A = (f(x) âf(a)) /(x â a), 'A' represents the average slope. Here (x-a) is used to represent the change in input values and f(x) â f(a) is used to denote the change in output of the function f(x).
This value is expressed in hours and represents the number of hours before the lamp is at half its original brightness. The expected life of a lamp will vary based on the lamp technology and the projector; however, most projectors offer about 2000 hours. The lamp's success rate is based on a bell curve, so that a majority of (but not all) lamps will meet the lamp life hours specified.
As the slide tray revolves, the number of the slide being projected will be opposite the gate index on the projector. You can obtain additional slide trays from your dealer; see back cover. Loading the Slide Tray. Check the bottom of the tray to make sure the INDEX HOLE is opposite the INDEX NOTCH.ush the lamp module all the way back into the projector until latched. Your projector is equipped with a code FHS projection lamp with a rated life of 70 hours. There are also two special-application lamps available. For longer lamp life (but less brightness), use a code EXY lamp with a rated life of 200 hours.
